Islandora, Daminion, Uploadcare, Nextcloud

Side by side on what we have verified on each vendor’s own pages. Where a fact was not checked, the table says so rather than leaving a blank that reads as “no”.

If the files genuinely cannot leave your infrastructure, this is not a close race — the platforms marked No below should not be on the call at all.

Verdict
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A DAM offered as both cloud and on-premise, aimed at small-to-mid teams that want fast metadata-driven search over large asset libraries and want files to stay on their own infrastructure.
A developer-first file upload and CDN/media-processing API for apps, pitched as a lighter, faster-to-integrate alternative to Cloudinary for teams that don't need its full DAM/video/AI stack.
A self-hosted file-sync and collaboration platform some organisations stretch into asset-library duty; tagging, batch metadata editing and dynamic tag-based collections are still limited or missing.

Most common complaint
Not checked
Like the platforms it competes with, it asks for a form submission before naming a price
The free tier is stated as personal use only
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner

“Not checked” means exactly that: we have not verified it, not that the platform lacks it. Every other value was read off the vendor’s own pages on the date shown on each platform page.

What to ask on the demo

One question per platform, drawn from what actually goes wrong with it — not a generic checklist. Vendors run the demo; this hands the agenda back to you.

Daminion Like the platforms it competes with, it asks for a form submission before naming a price — ask them to answer this in writing before the trial.
Uploadcare The free tier is stated as personal use only — ask them to answer this in writing before the trial.
Nextcloud It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner — ask them to answer this in writing before the trial.
